I don't think it's so much of a case of trying to "trick" the machines, as it is to get the clinic handling your sleep study to certify to the D.O.T. physician that you do not have sleep apnea,.....therefore taking responsibility for your diagnoses,......and in the event you do,.....God Forbid,.....fall asleep at the wheel,....have to have the insurance companies' investigators looking for another cause for the accident other than the residual effects of sleep apnea. You may be testifying,....under oath,...that you either do not have sleep apnea,...or that you were properly following doctors' instructions on how to treat sleep apnea. This is all about alleviating an employer's responsibilities in the event of an accident,.........And today,...in Congress,...the idiots, pushed by the ATA,.....are seriously considering INCREASING the hours of service to 80 hours in a 7 day period. This is the trucking companies' answer to a driver shortage,.........Increase the Working Hours,.....And if the driver has an accident,....it wasn't our fault we worked him so hard,.....he has "sleep apnea", and his "medical condition" caused the accident. I don't mean to denigrate the benefits of a C-PAP machine,.....Anyone sleeping in an oxygen-rich atmosphere has a wonderful nights' sleep,....any military pilot will tell you so,..........But I disagree with singling out our industry,...especially when we're not covered by the Fair Labor Standards Act of 1938,...and employers aren't penalized with overtime after 40 hours,....thereby putting a greater economic cost on employers to push guys 50, 60, 70,...or greater,...hours of work a week,......all because the perception of trucking, nowadays,....is nothing more than sweatshops on wheels,....and because of that perception,....employers can't find new hires............So,......Work the existing ones to death,...and blame that death on the employees "medical condition".
